The Acromioclavicular Joint
The AC joint is the part of the shoulder where the shoulder blade meets the clavicle bone and allows the two to move around each other It can be sprained, strained, dislocated and affected with arthritis and is a difficult joint to heal as it's used every time you move your arm.
It is also a very useful acupressure point for sore shoulders. In particular, if someone has rounded shoulders this is a good, but painful, point to press. If you carry your head forward 'in front of' the neck instead of on top of the neck , this point may also be painful. The greater the pain, the tighter the shoulder.
You can find it very easily yourself. Using your fingers, follow the trapezium muscle from the neck to the shoulder and where you feel it has narrowed into a V shape ... and press down.
If it's really painful...that's a sign to start concentrating on correct posture and also strengthening the shoulders and pectoral muscles, maybe under the guidance of a physiotherapist, especially if you have other musculoskeletal problems.
